Do I need original software after replacing hard drive?

[javisst]

Ok so the hard drive on my 2007 MacBook just died. I no longer have the original software that came with the MacBook, I only have the Snow Leopard upgrade that I bought last year. My question is, if I go ahead and replace the HD will I then need to install the full version of OSX that came with the computer, or can I just use the Snow Leopard upgrade?

Replace the HD and Load Snow Leopard. You don't need the full install of the original OS.
